FBlockAmountWeaponMult

Description	The amount of damage you block with a weapon is governed by your block skill and this setting. This setting reduces the amount of damage blocked when you block with a weapon rather than a shield. In other words, a value of 1.0 means that your weapon blocks as much damage as a shield, whereas a value of 0.5 means that your weapon only blocks half the damage of a shield.
Default value	0.5000

Note: the effectiveness of your weapon for blocking is also reduced by FBlockScoreNoShieldMult.
